UNITED STATES PATENT JOHN KAEGI, OF PHILADELPHIA, PENNSYLVANIA.

ROLLER USED IN MANUFACTURING WALL PAPER, 80c.

SPECIFICATION forming part of Letters Patent No. 651,359, dated June 12,1900. Application filed October 28. 1899. Serial No. 735,031. (Nomodel.)

To all whom it may concern:

Be it known that I, JOHN KAEGI, a citizen of France, residing atPhiladelphia, county of Philadelphia, and State of Pennsylvania, haveinvented a certain new and useful Improvement in Rollers such as areUsed in the Manufacture of \Vall-Paper, the of which the following is aspecification.

My invention relates to that class of printing-rollers on which themetal plates composing the design or pattern are secured for the purposeof printing wall-paper's. The rollers generally in use for this purposeare made of wood and are therefore liable to warp or twist or even splitwith changes of temperature, &c. This necessitates not only the expenseof a new roller, but the trouble of remounting the plates, which are,moreover, frequently injured by the operation.

The objects of my invention are, first, to provide a roller upon whichthe design-plates for printing or embossing wall-papers or other similarproducts are mounted and secured that will entirely prevent all risk ofinjury to the design through cracking or warping, and, second, toconstruct a roller that will not be affected by changes of temperatureand which will be effective in its operation, simple in construction,and inexpensive in manufacture.

I attain the objects of my invention by the use and construction of aroller, as shown in the accompanying drawings; but I wish it understoodthat my invention is applicable to all or any of the variousdescriptions of rollers used for the purpose of printing or embossingwall-papers and other decorative material.

- In the accompanying drawings, Figure 1 is a longitudinal sectionalview showing the gencral construction of the roller. Fig. 2 is a sideelevation of my invention, showinga few design-plates secured inposition.

each end and forming a roller resembling a spool, the intervening spacebetween the inner sides of the ends or flanges B B being completelyfilled up with plaster O, which when properly set andhardened is turnedoff perfectly round in a lathe, or it may be suitablymolded on, if foundpreferable to do so. Its outer ends next to the flanges are graduallychamfered off to a slight bevel even with the edge of the flanges B B. aa a show in section the design-plates secured to the surface of theroller with small nails Z) I), the space on the unoccupied surface ofthe plaster bed 0 between the design-plates and all other exposedsurfaces being coated with a compound of shellac or other equivalentresistant to the effects of water for the purpose of preserving theplaster bed C from all liability of absorbing moisture.

The diameter and thickness ofv the rollers and plaster are various andregulated by the nature and size of the design to be printed, largepatterns requiring greater circumferential area than smaller patterns,the thickness of theplaster bed 0 being regulated by size and strengthrequired.

It will be apparent that a roller constructed on or embracing theprinciples of my invention will entirely obviate the many disadvantagesattending the use of rollers as hitherto in use. I

Minor changes in the form, details, or construction may be resorted towithout depart ing from the principle or sacrificing any of theadvantages of my invention.

Having fully described the operation, construction, and objects of myinvention, what I claim as new, and desire to secure by Letters Patent,is w A roller for printing or embossing wallpapers, comprising in itsconstruction the combination of a metal roller A, having flanges B, B,and the space between the inner sides of said flanges B, B, filled inwitha composition of plaster, chamfered to a slight bevel even with theedge of said flanges B, its outer surface coated with a suitablemoistureresistant, and design-plates nailed on the outer surface of thecylinder formed thereby, all substantially as shown and described forthe purpose specified In testimony whereof. I have hereunto affixed mysignature in the presenceof two subscribing witnesses.

JOHN KAEGI.
